1 Claim. (Cl. 36-71) My invention relates to shoes and particularly toimprovements in sock linings which are particularly but not exclusivelyadapted for use in ladies shoes of the sandal type.

The principal object of my invention is to provide a sock lining havinga cushioning layer of yielding resilient material permanently associatedtherewith in such a way as to form a substantially unitary structurewhich will allow the lining to be removed from a shoe without damagethereto or to said cushioning layer.

I accomplish this object in the manner and by the means described belowand illustrated in the accompanying drawing in which- Fig. 1 is a topplan view of the lining;

Fig. 2 is a perspective view of a portion of the lining with the partsthereof separated to show the inner construction;

Fig. 3 is an enlarged section of Fig. 1 in the plane 3 3; and

Fig, 4 is a perspective view of a sandal having my sock lining therein.

Referring to the drawing:

My sock lining comprises a thin, flexible strip of leather 1 which issubstantially coextensive with the inner surface of the sole of the shoeto which it is to be attached. 2 is a second strip of leather overlyingand substantially coextensive with those zones of the strip of leather 1which extend between the phalanges and the heel of the wearer of theshoe. In other words, it underlies the metatarsus.

Between the strips 1 and 2 is a unitary layer of yielding, resilientmaterial of uniform thickness, preferably a sheet of foam rubber 3,having its marginal edges spaced inwardly from the marginal edges of thestrip 2 but which, otherwise, may be substantially coextensive with thestrip 2, or terminate at the rear in about the position shown by the dotand dash line 4 in Fig. 1.

In order to secure the portions 1 and 2 together with the layer of foamrubber 3 therebetween, I use an inner and an outer line of stitching 5and 6, respectively, which are substantially parallel to each other andadjacent the marginal edges of the layer 2. The marginal edges 7 of thelayer of rubber are disposed between the lines of stitches 5 and 6.Thus, the outer line of `stitches passes only through the upper andlower layers of leather closely adjacent their marginal edges and isclosely adjacent but beyond the marginal edges of the layer of rubber.The

inner line of stitching 5, however, passes through both of the leatherportions and also through the layer of rubber, as best shown in Figs. 2and 3.

From the foregoing, it will be apparent that my sock lining is a unitarystructure which may be adhesively secured to the inner surface of thesole of a shoe and removed therefrom, when necessary, without damage tosaid lining.

The leather portions have their smooth sides exposed on the top of thelining and, if the portion 1 is black, a very attractive appearance isgiven to a shoe by using a white leather for the portion 2.

While I have described my invention in its preferred embodiment, it isto be understood that the words which I have used are words ofdescription rather than of limitation and that changes, within thepurview of the appended claim, may be made without departing from thetrue scope and spirit of my invention in its broader aspects.

What I claim is:

An orthopedic sock lining for a shoe of the sandal type; said liningcomprising a rst portion of thin, flexible leather conformingsubstantially in size and shape to the inner surface of the sole of saidshoe; whereby it may be adhesively secured thereto and substantiallycoextensive therewith; a second portion of thin, flexible leatheroverlying said iirst portion, having its lateral edges closely adjacentthe lateral edges of said iirst portion and extending longitudinallybetween a zone adjacent the heel of the wearer and a zone which willunderlie and extend somewhat beyond the metatarsus of the wearer; alayer of sponge rubber of substantially uniform thickness between saidfirst and second portions of leather and substantially coextensive withsaid second portion from the forward end thereof to at least the rear ofthe metatarsus; said portions of leather being secured together by afirst line of stitching closely adjacent the edges of said secondportion but beyond the edges of said rubber; and said layer of rubberbeing securely held in fixed position between said portion of leather bya second line of stitching spaced from but substantially parallel tosaid first line and extending through said leather portions and throughsaid layer of rubber in spaced relation to the edges of said layer.
